SPECIFICATION forming part of Letters Patent No. 739,988, datedSeptember 29, 1903.

Application filed October 3, 1902.

To all whom it may concern:

Be it known that we, ADDISON A. OOBURN, residing at Coldspring, andFRANK I-IARNDEN, residing at Palmyra, in the county of J efferson andState of Wisconsin, citizens of the United States, have invented a newand useful Band-Cutter and Self-Feeder for Corn Husking and ShreddingMachines, of which the following is a specification.

Our invention relates to band-cutters and self -feeders for corn huskingor shredding machines in whichbundles of corn are thrown into aconveyer, where the bands are cut and the stalks of corn are spread outevenly while being carried to and fed into the husking or shreddingmachine; and the objects of our invention are, first, to provide aconveyer in which the chains doing the greater part of the work can beadjusted without interfering with the other chains; second, to furnish aband-cutter which will adjust itself automatically to different-sizedbundles, and, third, to supply a feed-roller and spreader which will.work uniformly upon a variable quantity of corn passing through themachine. We obtain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a view of the conveyer withthe band -cutter, spreader, and feed roller removed, so as to-show thearrangement of the carryingchains. Fig. 2 is a view of the bandcutter,Fig. 3 of the spreader, Fig. 4 of the feed-roller, and Fig. 5 of thecomplete machine with all its parts in place excepting B B.

Similar letters refer to similar parts throughout the several views.

The table A with its upward projecting wings B B constitute the frame ofthe machine, and is attached to the huskin g or shredding machine at itsend ain any suitable manner so that it will communicate with thefeedopening of the husker or shredder. The shafts b, b, and b extendacross the table A and rest in bearings at each end secured to theframe, in which they are revolved by power communicated by any suitablegear. The shaft 1) has four sprockets or pulleys c, c, c, and c; b hastwo, at d, and b has two, 6 e, for the conveyers ff and gg, which areendless chains passing over and under the table semi No. 125,841. (Nomodel.)

A, moved forward toward the end a by the revolution of the shafts b b b.

The band-cutter O is .a cylinder having knives h arranged radially uponthe circumference and arms ii at each end hinged to its shaft j. Theother ends of the arms 112' are hinged to the shaft of the spreader D,so that C rides upon the bundles passing under it and adjusts itself tothe size of each bun'dle. G is driven from the shaft k by belts workingon the pulleys NH, and its weight is partially sustained by the springsm m, which prevents its pressing too hard upon the bundles. Knives 0 1;,&c., are also placed on shaft 6 as auxiliary cutters.

The spreader D consists of the shaft 10, having vanes 01. n n n n, &c.,arranged radially upon it and rests in bearings 0 o, secured to theframe A. Each of the vanes 72 n, &c. consists of two parts, one ofwhich, 10, divides the stalks and the other of which, q, spreads them.The dividers p are flat sections of a disk and stand in planesperpendicular to k, and all those on one side of the center of 7c arebent slightly to the left and all those on the other side are bentslightly to the right, forming the spreading-vanes q q g, &c. Power isapplied to 70 by a pulley 0", driving D in the direction indicated bythe arrows in the drawlugs.

The feed-roll E is a cylinder upon a shaft 5, having arms 25 thinged'ateach end. The opposite ends of t t are hinged to the shaft 70, so thatthe roller E Works up and down and adjusts itself to the quantity-ofstalks passing under it. E is driven by belts upon pulleys u 'u. u u andrevolves in the direction indicated by the arrows.

Having thus described our invention, What we claim as new, and desire tosecure byLetters Patent, is-

1. A stalk-spreader comprising a shaft, a central divider-diskth ereonin a plane perpendicular to said shaft, short inclined spreadersectorsextending from both sides of the disk, to divider-sectors parallel tothe plane of said disk, and other inclined spreader-sectors eX- tendingfrom these sectors to other sectors parallel to the central disk wherebya pair of oppositely pitched interrupted spirals are formed.

the lower sides of the band-cutter, spreader and feed-r011 in the samedirection.

In testimony whereof we have signed our names to this specification inthe presence of I 5 two subscribing Witnesses.

2. In a band-cutter and feeder for cornhusking machines the combinationof a table carrying feed-chains, a shaft thereover carryin a spiralstalk-spreader, a pair of arms 5 pivoted on said shaft and extendingforward therefrom oarryin at their free ends a cylinder provided Wifilband-cutting knives, a

second pair of arms pivoted on and extending rearward from said shaft,carrying at Vitnesses:

to their free ends a feed-roller, with means for MARTIN MASON,

driving the upper run of the feed-chains and N. O. NELSON.
